SPECIFICATION forming part of Letters Patent No. 662,150, dated November20, 1900.

Application filed March 15,1900. Serial No. 8,716. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM W. MCCOR- MICK, a citizen of the UnitedStates, residing at 135 Third street, in the city of Santa Rosa, countyof Sonoma, and Slate of California, have invented certain new and usefulImprovements in Throat-Shields; and I do hereby declare the following tobe a full, clear, and exact description of the said invention, such aswill enable others skilled in the art to which it most nearly appertainsto make, use, and practice the same.

This invention relates to improvements in surgical instruments, and moreparticularly to a shield for introduction into the thorax of a personbeing operated upon for any nasal trouble.

In the drawings, Figure 1 is an elevation of the invention as applied tothe throat of a person. Fig. 2 is a rear view of the same. Fig. 3 is across-section of the same.

The invention has for its object to provide a shield which will preventthe introduction of hemorrhage or blood into the thorax or bronchi ofthe person being operated upon for any nasal ailment, while at the sametime providing means for supplying air for breathing purposes, which isintroduced from beyond the mouth; also, to provide means for carryingthe blood off, so that the same is not precipitated into the mouth ofthe patient when being operated upon; and the invention consists inprovidingashield constructed in the shape substantially shown in thedrawings and of any suitable material-such as vulcanized rubber,aluminium, orsimilar material-Which is stamped to provide acavity C inthe rear of the shield or on the side of the shield toward the thorax.The exterior of the shield A is such as will most readily accommodateitself to the posterior cavity of the mouth. From the cavity C isextended a flexible tube or pipe B, adapted to extend beyond the lips ofthe mouth. It is through the pipe or pipes B that air is drawn from theoutside. The front of the shield A is shaped so as to form a valley orcurved portion to direct the hemorrhage into the pipe D, which isextended beyond the outer edge of the mouth and which may be carried toa suitable receptacle for the hemorrhage.

In operations of the nature specified it has been proven in the pastthat the hemorrhage has been exceedingly difficult to handle, as byreason of the position of the patient the blood has access to thethorax, in many cases causing what is termed gagging or exceedingdiscomfort both to the patient and to the operator.

The shield A shown in the accompanying drawings and herein described isin such shape that when placed in position the contractile action of themuscles at the rear of the mouth, together with the natural suctionaction of the lungs and organs connected therewith,will hold the samefirmly in place. By providing the drainage-tube D all the blood iscarried away from the thorax and the difficulties and inconveniencesspecified are avoided. At the same time by reason of the introduction tothe rear of the shield A of the pipe B a sufficient supply of air issupplied to the lungs. With an appliance of this nature in position itis possible for the operator to work with greater convenience both tohimself and to the patient.

Having thus described this invention, it is claimed 1. In an instrumentof the character specified, the combination with a suitable shieldadapted to close the entrance to the thorax of the patient, of a tubeopening upon the rear side of said shield and extending forwardlytherefrom, whereby air is supplied to the patient through said tube andhemorrhage from the nose'is kept from entering the thorax; substantiallyas described.

2. In an instrument of the character specified, the combination with ashield adapted to close the entrance to the thorax of the patient, of adrainage-pipe connected to the forward surface of the said shield andadapted to collect and deliver the hemorrhage beyond the mouth of thepatient, and a suitable tube opening upon the rear side of the saidshield and extending therefrom to a position forward and out of the pathof the hemorrhage, said shield having a raised portion, or recess, inits rear surface to receive the said secondnamed tube; substantially asdescribed.

In testimony whereof I have hereunto set my hand this 2d day ofFebruary, 1900.

WILLIAM W. MCCORMICK.
